Specification of Letters Patent No. 26,667, dated anuary` 3,

To all whom it may concern.'

Be it known that we, J AMES GARDETTE and HENRY RANCE, both of New Orleans, in the parish Yof Orleans and State `of Louisiana, have invented a new and useful Machine for Changing Water into Mist for Medicinal Purposes; and we do hereby declare that the following is a full, clear, andexact description thereof, reference being had to the accompanying drawings, forming apart of this specification, in which- Figure l represents a front elevation of the machine. Fig. 2 is a transverse vertical section taken through the red line of Fig. `l.

Similar letters of reference indicate corresponding parts in both figures.

Physicians have sought some means of administering medicines to and through the respiratory apparatus, and the only method heretofore imagined has been to employ gases or liquids evaporated for inhalation by the application of heat, so that by boiling the liquid the vapors may be inhaled. This method is very objectionable in many cases and it is very desirable to obtain a means of inhaling any medicine at any determinate degree of temperature, even below the point of evaporation, and even such medicines as cannot be evaporated.

Our invention consists in the employment of aV rotary wheel with hollow radial arms terminating in very small orifices, through which the liquid is thrown in jets by centrifugal action, and it further consists in arranging on the ends of independent radial arms, which are attached to a solid hub rotating in an opposite direction to the first wheel deflecting plates, against which the jet of liquid is thrown which serve thepurpose of dispensing and diffusing the particles of liquid throughout an apartment so that they `can be taken into the respiratory appara-tus without inconvenience, as herein after fully described.

A A represent two standards fixedto a base, B, and'upon these standards are supported the following devices: D is a reservoir for containing the medicinal compounds, which are to be vaporized or mistified, and E is a tube communicating with the bottom of said reservoir, and furnished with a stop-cock, F. This tube is bent at right angles, and the angle secured to the top of the standard, A', by suitable bolts as shown at G, Fig. The` bent portion,

proceeds out about `midway between "the".

standards, A A', and serves as the aXial support for the tube,H, of the radial "arms,

J. These arms, `J, are all` made hollow, as clearly shown by Fig. 2, ofthe drawings, and terminate in very` small orifices, afa, through which the liquid which flowsfrom the reservoiigis dischargediny `line `jets 'as u the arms are swiftly rotated.

directions to each other by means `of `the i belts, e f, which pass over the pulleys, b and i c, and over the two-belt wheel,`R, thebelt, f, i

of the arms, J, andas itis thrown olii' it struck by the plates, If, and liies off inthe form of line mist,wh1ch1 soon charges the air of the entire apartment.

In the use of this apparatus what may fbe` considered very materialand highly `important is, that no decomposition of the `inn-1 gredients takes place, asundoubtedly must` arise when heat is applied tovaporize the compounds.
